New ‘Doctor Who’ Season 9 Trailer: Dark Times & More Daleks Ahead For The Time Lord

Season 9 of the current incarnation of long-running Time Lord series Doctor Who will debut on September 19 on BBC America. The last time we saw the good doctor was in a Comic-Con trailer last month. A new reel has unspooled today with Peter Capaldi reprising the role he first took over last year.

Guest stars this season include Game Of Thrones’ Maisie Williams and League Of Gentlemen‘s Reece Shearsmith, along with Rebecca Front, Rufus Hound, Paul Kaye, Elaine Tan, Neet Mohan, Bethany Black, Paul Courtenay Hyu, Joivan Wade and Sophie Stone. Michelle Gomez is due to return as Missy (aka The Master) in the season premiere along with regulars Capaldi and Jenna Coleman as companion Clara Oswald. While the SDCC trailer showed GoT‘s Williams, today’s peek teases her still-unexplained role in the new season.

In the new season — see the new key art at right — the Doctor and Clara embark on a journey that takes them to deadly alien planets, creepy underwater bases, Viking villages, a global Zygon uprising and through hidden alien dens, to the very end of time itself. Meeting monsters old and new, the Doctor will come face to face with Missy, a city of Daleks, deadly mercenaries called the Mire, terrifying ghosts and more.

Things kick off with a two-parter, “The Magician’s Apprentice” and “The Witch’s Familiar,” written by lead writer and showrunner Steven Moffat and directed by Hettie Macdonald.
